This README summarizes many of the data products.
Please report any problems (e.g., missing or corrupt data) to Ian Stephens: iwstephens@gmail.com

The MASSES full data release is described in Stephens et al. (2019).
Refer to Table 1 of the above paper for "Other Names" of these sources (e.g., NGC 1333 IRAS 4A).

Each target has line-subtracted continuum and continuum subtracted spectral line visibilities (uvdata). 
Continuum and spectral lines images are mapped toward each source.
For all images, there are two available robust weightings (-1 and 1).
robust-1 provides higher resolution while robust1 is more sensitive to large scales.
Images are delivered that are primary uncorrected and primary corrected (pbcor).

Continuum are available as fits images. Fits cubes are available for all spectral lines.
Spectral lines at 1.3 mm: 12CO21, 13CO21, C18O21, N2DP
Spectral lines at 850 um: 12CO32*, HCOP43*, and H13COP43
*12CO32 and HCOP43 are missing for the pointings:
Per-emb-8 and Per-emb-55

*Per-emb-7, Per-emb-15, and Per-emb-43 were not observed with SWARM at 850 um, and thus contain only 1.3 mm SWARM data.

Spectral lines imaged at 1.3 mm: c3h2, dcn32, dcop32, h2co303, h2co321, h2co322, sio54, so5544*, so5645	
Spectral lines imaged at 850 um*: 34so9887, cn5232, cn7252, cs76, dcn54, dcop54, h13cn43, hc15n43, hc18o43, hnc43, ocs2827, so7867, so8877, so9887
*dcop32, so5544, and 850 um data do not have extended tracks and thus are at coarser resolution.
See Stephens et al. (2019) for full description of line transitions.

Calibrated SWARM visibility data (not continuum subtracted) are also included for many pointings.
Pointings that have subcompact (SUB) SWARM uv data are the same as the ones with imaged SWARM data.
Pointings that have extended (EXT) SWARM uv data are:
